These systems often require larger bonding conductors because they may carry neutral current under certain fault conditions. Standard PME sizing tables often mandate a minimum of based on the incoming supply size.
When sizing an earth cable, several factors need to be considered: earth cable sizing
Earthing, also known as grounding, is a critical aspect of electrical safety. The primary purpose of earthing is to provide a safe path for electrical currents to flow to the ground in the event of a fault, thereby protecting people and equipment from electrical shock. A crucial component of an earthing system is the earth cable, which connects the electrical installation to the earth. Proper sizing of the earth cable is essential to ensure that it can handle the fault currents and provide a reliable and safe path to earth. The primary purpose of earthing is to provide
